In this paper, the first order approximation theory of dynamic logging is obtained by using the geometrical factor theory in downhole condition and RC network theory.

本文用井条件下的几何因子理论和RC网络的单位脉冲响应给出了动态测井的一阶正演理论。

The crustal stress problem is major difficulty during drilling at the south area of the Base and is the fundamental reasons of the complicated downhole condition during drilling .

地应力问题是南缘地区钻井的主要难点，也是钻井过程中井下复杂的根本原因之一。

However, the condition often does not allow Wells to pump fluid into the layer below the place, then consider the use of downhole gas separator.

但井的条件常不容许将泵置于流体进入层下方，则考虑用井下气分离器。
